Ring Sizing Insert With Interference Fit Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring sizing solutions are limited in their ability to effectively reduce the size of rings to fit smaller fingers, toes, or other anatomical features, as they often require customization or do not provide a snug fit.
Innovation Solution
A ring sizing insert comprising a pair of elongate members, each shaped to partially extend within the ring's opening, with one member featuring outward protrusions and the other member having recesses for an interference fit, forming a receptacle that receives the ring band and includes catches to extend around the ring, thereby reducing the ring's effective size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a ring reducer with a reducing web is used to fit a larger ring to a smaller finger, then the ring size is reduced, but the device requires customization by trimming the reducing web with a knife
Solution Approach 1:
The ring sizing insert is divided into two separate elongate members that can be independently manufactured and then assembled together. This segmentation allows each member to be produced with precise dimensions without requiring post-manufacturing customization, while still achieving the desired ring size reduction when the members are coupled together.
2Adaptability or versatility
If an adjustable finger ring with a resilient shank and ball element is used, then the ring can be adjusted to different sizes, but the device becomes more complex with multiple components
Solution Approach 1:
The elongate members incorporate dynamic elements such as resilient portions and movable catches that allow the insert to adapt to different ring sizes and configurations. This provides adjustability and versatility while maintaining a relatively simple overall structure, avoiding the need for excessive components.
3Strength
If a ring guard with massive beam parts is used to sustain pressure, then the structural strength is improved, but the device becomes more massive and complex
Solution Approach 1:
The insert employs local quality by concentrating strength where needed - the elongate members have specific structural features like protrusions, recesses, and catches at critical locations to sustain ring pressure and secure the fit, rather than making the entire device massively thick throughout. This provides necessary strength while minimizing overall complexity and mass.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The insert provides a secure and adjustable means to reduce the ring size, allowing it to fit smaller anatomical features by forming a snug receptacle that accommodates the ring band, ensuring a comfortable and secure fit.
Implementation Method 1
A second of the elongate members has a recess shaped to selectively receive the protrusion

AI summary
There is provided a ring sizing insert. The insert includes a pair of elongate members each of which is shaped to partially extend about the opening of a ring. A first of the elongate members includes a pair of spaced-apart, outwardly extending protrusions. A second of the elongate members includes a pair of spaced-apart recesses shaped to selectively receive respective ones of the protrusions. The elongate members when coupled together form a receptacle within which a portion of the band of the ring fits.
